Considered the greatest satire ever written in English, Jonathan Swift's Gulliver's Travels chronicles the fantastic voyages of Lemuel Gulliver, principally to four marvelous realms: Lilliput, where the people are six inches tall; Brobdingnag, a land inhabited by giants; Laputa, a wondrous flying island; and a country where the Houyhnhnms, a race of intelligent horses, are served by savage humanoid creatures called Yahoos.
